NoClassDefFound-wrong name

[saipraneeth nallapareddy]

i am working with web services and i am trying to test them, i am shocked to get the following exception, the thing is there is a Test.java file in a package and build the class using ant build.xml the Test.java consist of main method but i am facing the following error and i checked many a times the source file name with the class name, and named them by copying from what i have typed but still

What is exactly the command that you typed in to run your application? Try this instead:

java -classpath build\classes org.apache.ws.axis2.Test

[saipraneeth nallapareddy]

no change

[David Newton]

What is your directory structure (source and build), and how are you trying to run it? It's definitely a classpath issue; it looks like it's trying to run something with the classpath set up the hierarchy too far.

[saipraneeth nallapareddy]

here is my directory structure

                        Test.java

In that case, the command given by Jesper should work assuming that the current directory is the top-level one (in which "src" and "classes" reside).

[saipraneeth nallapareddy]

when i am running through the prompt by changing the directory to the appropriate location and run in the usual way i am getting the error which i have specified earlier but when i am using an IDE i am getting the following error.

    Exception in thread "main" java.lang.Error: Unresolved compilation problem: 
	The constructor HelloServiceStub() refers to the missing type AxisFault

	at org.apache.ws.axis2.Test.main(Test.java:8)

[David Newton]

"The usual way"? How would I know what your "usual way" is? TellTheDetails. Don't make us guess what you're doing--it makes it very painful to help.

[saipraneeth nallapareddy]

sorry if i am providing less information

location:\ >java Test   

    package org.apache.ws.axis2;
import org.apache.ws.axis2.HelloServiceStub.SayHello;
import org.apache.ws.axis2.HelloServiceStub.SayHelloResponse;
public class Test
{
	public static void main(String[] args)throws Exception
	{
		HelloServiceStub stub=new HelloServiceStub();
		SayHello request=new HelloServiceStub.SayHello();
		request.setArgs0("Hello world");
		SayHelloResponse response=stub.sayHello(request);
		System.out.println(response.get_return());
	}
}

[David Newton]

And your classpath is? Where are you in your directory hierarchy when you try to run?

[saipraneeth nallapareddy]

HelloService is the root directory

                        HelloServiceStub.java
                        Test.java

  

when i am running the File Test.class i will in the location

drive:\XXX\HelloService\build\classes\org\apache\ws\axis2>java Test  

[Ulf Dittmer]

java Test

This can't possibly work, since the class is part of the org.apache.ws.axis2 package. Try "java org.apache.ws.axis2.Test" instead.

You need to change into the "HelloService" directory first, and then the command posted by Jesper will work.

[saipraneeth nallapareddy]

i have tried in your way

   
drive:\XXXX\HelloService\build\classes\org\
apache\ws\axis2>java org.apache.ws.axis2.Test
Exception in thread "main" java.lang.NoClassDefFoundError: org/apache/ws/axis2/T

[David Newton]

*sigh*

[Sridhar Santhanakrishnan]

change to

drive:\XXXX\HelloService

and then run

java -classpath build\classes org.apache.ws.axis2.Test

[saipraneeth nallapareddy]

this is really the problem with the classpath and the location i am using, the one you have said is working.
even earlier one of the member asked me to do the same but the location made the difference.
thanks for every one who took the risk and pain to help me.

[Campbell Ritchie]

Are you running from Eclipse? That is the only place I have seen Unresolved compilation problems.

[Rob Spoor]

Or any other IDE that allows you to run code without solving compiler errors. And this is why you never should run an application while there are still compiler errors; you should always solve these before trying to run your application. Any application with compiler errors will always be broken.
